  • Detergent tablets are often used for washing crockery.
  • the tablet is inserted manually into the detergent dispenser and, after the lid connected to the detergent dispenser is opened, falls into a zone of the dishwasher in which the washing water dissolves the tablet to wash the crockery.
  • the tablet after the lid is opened, often does not fall into a zone of the dishwasher that is suitable for the complete dissolution thereof. Thus, at the end of the washing step, the tablet is not completely dissolved, with unpleasant consequences due to the poor washing of the crockery.
  • EP2138088 describes a detergent dispenser where the tablet is prevented from falling into the dishwasher by a grille or by two vertical elements.
  • an arrangement for a dishwasher comprises a detergent dispenser
  • the detergent dispenser comprises a set of tablet restraints for retaining a detergent tablet in a cavity of the detergent dispenser; and a water outlet configured to release water to a top section of the detergent dispenser.
  • water can be supplied to the detergent dispenser in a controlled manner.
  • a lid of the detergent dispenser is opened, water can flow onto the detergent tablet placed in the detergent dispenser from the water outlet above the detergent dispenser, which outlet releases water onto the door or the top of the dispenser in a controlled manner.
  • the detergent tablet can thereby be dissolved completely in a controlled manner while kept in the detergent dispenser.
  • the tablet restraints are located at a bottom surface of the cavity in the detergent dispenser.
  • the restraints can be made small and the detergent tablet can be easily placed in the detergent dispenser.
  • the bottom surface has a sloped surface.
  • the tablet restraints are formed as teeth provided with an upwards facing portion forming an acute angle. The upwards facing portion is adapted to form a support against which a detergent tablet can rest when placed in the cavity of the detergent dispenser. Hereby the risk that the detergent tablet leaves residues in the detergent dispenser is reduced.
  • a detergent dispenser for a dishwasher has a set of teeth located at a bottom surface of the detergent dispenser for retaining a detergent tablet in the detergent dispenser.
  • the teeth are provided with an upwards facing portion forming an acute angle, wherein said upwards facing portion is adapted to form a support against which a detergent tablet can rest when placed in the detergent dispenser.
